To the Winnovation guys regarding the hex broach through the UHMW wheels.1251 has a lot of R&D into UHMW material espeically regarding using them as wheels, see our 2007 robot. I can tell you the hex will not last especially playing as many matches as you guys do during a season. My suggestion is developing another keying method, bolting on alumnium hex hub adapters or just making the wheels out of alumnium. Also, avoid pressing things such as bearings or hubs into the UHMW in drive applications as the material is oil impregnated which makes doing something like that difficult, it is doable but on something that needs to be as reliable with as much torque as a drive system I don't recommed it. Overall the design is nice and clean looks like something great to build on. Good luck in 2011.
